It is Cambridge Yr 11 Ext 1 Ex. 17F Q6

Furthermore, the fx-92B Secondaire can do Algorithms: But going back to Math Box, this is on most of them and gives options of Dice Roll and Coin Toss. You can choose 1,2 or 3 dice or coins and up to 250 attempts. It tabulates results and also gives an animated screen as it rolls the dice or...

So what functionalities would you want from the other emulators? Well as we have already seen, the fx8200 AU, TI-30XB MultiView and TI-30X Plus MathPrint won't do cos(72o) whereas the classpad app does: The TI-Nspire CX II-T emulator also does it: One thing I like in TI-Nspire CX II-T which...

Although it looks better in the app for fx8200 AU it seems that the app version does not have quite as many options for model selection as in the web-based version. Here is the current model selection in the ClassWiz Calc App Plus: This may change in the future though.

There is an iphone app that emulates the fx8200 AU. It is called the ClassWiz Calc App Plus. You just log in with the same login for the web-based one and it looks like this: This looks much better full screen on the iphone than the web-based version. It works in ipad too. There is also an...

For a triangle, n=3 \color{red}\text{Area}(S)=\frac{3\times16^2}{2}\sin\frac{2\pi}{3}=192\sqrt3

And if you don't know where (nr2/2)sin(2π/n) comes from, I assume you know about (1/2)absinC, yeah? Just apply it to this: in the circle like this: And just as an aside, you can use the area of a regular apeirogon (regular polygon with \infty sides) to prove the area of a circle...

i. The given vertex is 2eπi/6. Hence the other 5 are z=2e(2k+1)πi/6, k=±1, ±2, -3. ii. z4=16e2πki/3, k=0, ±1 giving the vertices of an equilateral triangle circumscribed by a circle with radius 16. Hence Area(S)=(3x162/2)sin(2π/3)=192√3 (since the area of a regular n-gon circumscribed by a...

A angle of a revolution is 2π so they add 2π/6=π/3

I found a proof which is attached. There might be an easier way to do it, or at least a simplification of the attached proof.

Is that the second edition? I have one too. I would keep that because it can do something the 8200 AU can’t - measurement conversions. Also, did you know in the 100 AU second edition there is a secret key combination that reveals the Calculator ID. The same is true for the 82 AU plus ii second...

It gives access to all these: Supported models: fx-82CW / 85CW / 350CW / 570CW / 991CW fx-82EX / 85EX / 350EX / 570EX / 991EX fx-8200 AU fx-82AR X / 95AR X / 570AR X / 991AR X fx-880BTG / 580VN X fx-82CE X / 85CE X / 350CE X / 991CE X fx-82DE CW / 85DE CW / 87DE CW / 991DE CW fx-82DE X / 85DE...

How to get the emulator There are 3 ways to get the emulator. Method 1 with a real calculator If you already have the real calculator you can press the [HOME] [SETTINGS] buttons on the calculator to get the Calculator ID. This entitles you to get a free license which lasts 7 years. This would...

I think that although the classpad is better at exact values than the fx8200 AU as we have seen - it turns out that it's not much better. It can do cos(π/8), cos(π/10), cos(π/12) but not cos(π/15): So even classpad has it's limitations. Mathematica did cos(π/15) like this: fx8200 AU can't...

So I did an experiment, this time in radian mode to see what would happen with the classpad and then with the fx8200 AU for cos(π/x) for x=4,5,6 and this is what I got: So you can see the difference for cos(π/5)

It was supposed to come out in July, but retailers are selling it now.

I made it do this though by turning on the Verify mode: It's not as good as the classpad version though. Even the old calculators could do this - for example:

I coudn't get it to do cos(72o) in standard form. I tried out a few of the other CASIO emulators as well listed above and they coudn't do it either I tried doing it on the Texas Instruments emulators for TI-30XB MultiView and TI-30X Plus MathPrint and they couldn't do it either. I think they...

I thought it comes with a AAA battery, not button battery. It's on page 110 of the user guide from https://casioeducation.com.au/wp-content/uploads/2023/05/fx-8200-AU_User-Guide.pdf

And what I found out in the emulator is that you have access to emulators for all these calculators too: That's 39 emulators in 1 I'll stick with fx-8200 AU for now though. It used to be that the emulator could only run on a Windows or Mac computer. But now you can put it on your...
